Wanted to provide an update here.
First of all, if you are running into bugs (like all your photos have the same date) please reach out to support. If you’re on mobile, you can shake your device, if you’re on the web, you can use the settings cog.
As for the ability to change metadata on photos, that’s not something we currently have on the immediate roadmap.

I agree with the author of the Idea, actually that makes OneDrive impractical to be my "go to" option for searching my photos when I need them later. This problem mess up our photos timeline big time....
